God calls people into different works. In the midst of this diversity, a common thread unites all the work—men ought to do all they do to the glory of God.
How would making your motive match the Lord's motive change how you approach the Christian life (from witnessing to praying to Bible reading and so on)?
It has always been easier for man to see the problems in the lives of others. In fact, the problems we most easily identify in others are often the sins with which we personally struggle. Oftentimes, believers see these problems and immediately rush to rebuke or admonish those in error without considering their own lives first. According to Galatians 6:1, those overtaken in a fault should not be admonished until the restorer has first considered himself. The Bible says, “lest thou also be tempted.” 1 Corinthians 10:12 contains a similar principle and admonition: “Wherefore let him that thinketh he standeth take heed lest he fall.” Believers should not be easily deceived by their own conditions and must be willing to call their own standing into question first. Remember that those who have fallen should serve as a warning to every believer.
